A 2.7MHz OSCILLATOR IS NOW INCLUDED TO REPLACE THE INTERNAL VFO.
THIS GIVES COMPLETE CONTROL OF FREQ, ACCURACY, & STABILITY TO THE VFO 1000.
A SWITCH IS INCLUDED TO SWITCH BACK TO THE RECEIVER'S INTERNAL VFO IF DESIRED.
INSTALLATION IS BY SLIPPING AN EYELET WITH A WIRE ATTACHED OVER PIN 1 OF THE PTO TUBE.

The VFO 1000/Collins is a direct digital synthesizer programmed to enhance the operation of Collins S-Line receivers.  There are 30 tunable memories that are programmed to provide the functions of VFO, MEMORIES, and GENERAL COVERAGE reception. The first 6 memories are factory assigned for the 80 meter to 10 meter ham bands. The remaining bands are assigned to provide general coverage of the shortwave bands. They can be easily user re-assigned in any way you wish up to 30MHz.  Some memories could be your favorite net frequencies, others could be used for general coverage of the shortwave broadcast bands.  The encoder has 5KHz, 1KHz, 100Hz, and 10Hz tuning steps, and can be locked to prevent accidental changes.  An  LED indicates when the encoder is active.  There is a 50KHz step available in the setup mode to speed-up  frequency entry.     The LCD is blue backlite with white characters.  No mods to the receiver are required.

If you prefer traditional Collins tuning, switch the 2.7MHz oscillator OFF and set the VFO display to the low end of the desired 200KHz segment, then  tune using the receiver tuning knob.  The operating frequency in this case is the VFO display plus the receiver dial.  The tuning knob on the VFO can be disabled to prevent accidental changes.

Installation of the VFO 1000 is by removing the 6U8 HF oscillator tube, inserting the included adapter in the socket, then insert the 6U8 in the adapter.  A cable goes from the adapter to the main unit.  A switch on the adapter switches between the ham band crystals and the shortwave unit.
